While I think paleo diets are going too far in the wrong direction in the search for a dietary solution, I emphasize with your observed problems. It seems that sugar is simply added by default to far too many foods. The biggest thing I would suggest is to avoid canned foods, especially beans. Buy dried beans instead. They don't take that much effort to cook, the only thing is that you need to remember to soak them overnight (and discard the soaking water) before cooking. As an added bonus, dried beans, lentils, chickpeas and so on are inexpensive and widely available. You could also get a pressure cooker, which is just a good idea in general, and will allow you to cook beans directly in about an hour.
